ankoles [38]

Answer:

96m

Explanation:

Using SUVAT:

s=? u=0 a=3 t=8

s=ut+0.5*at^2

s=0.5*3*8^2

s=96m

A 544 g ball strikes a wall at 14.3 m/s and rebounds at 14.4 m/s. The ball is in contact with the wall for 0.042 s. What is the
Nezavi [6.7K]

Answer:

F = 371.738\,N

Explanation:

Let assume that ball strikes a vertical wall in horizontal direction. The situation can be modelled by the appropriate use of the definition of Moment and Impulse Theorem, that is:

(0.544\,kg)\cdot (14.3\,\frac{m}{s})-F\cdot \Delta t = -(0.544\,kg)\cdot (14.4\,\frac{m}{s} )

F\cdot \Delta t = 15.613\,\frac{kg}{m\cdot s}

The average force acting on the ball during the collision is:

F = \frac{15.613\,\frac{kg}{m\cdot s} }{0.042\,s}

F = 371.738\,N

Many people love roller coasters. Some people call them scream machines. They agree that
Alex73 [517]

Answer:

There is some sort of "rollers" on the trail part that is used to make the roller coaster move when it is going up. Then because of that, the speed gets quicker when it drops down, so then it could move for a longer time until it reaches the next arch.

Explanation:

hope this helps :)
